I have a sealed tank positioned on a high surface filled with water and nitrogen gas above. Tank manometre shows pressure of 0.5 bar. What is the pressure applied to the water in tank? Is it 0.5 or 1.5 bar?

2$\begingroup$ Is the manometer 'gauge' or 'absolute'? 'Gauge' is relative to the environment, 'absolute' is, well, absolute. $\endgroup$– Jon CusterCommented Jul 19, 2022 at 13:31

$\begingroup$ The manometer is indicating gauge pressure so the 0.5 bars is probably gauge. The absolute pressure is probably 1.5 bars. $\endgroup$– Chet MillerCommented Jul 19, 2022 at 13:55

Indicated gauge pressure ( relative to outside ) acts both on air and water.
Both are fluids obeying Pascal's Law with a uniform pressurized state.
